New Guinea impatiens plant named ‘Danharltpk’

ABSTRACT

A new and distinct cultivar of Impatiens plant named ‘Danharltpk’ characterized by having large, round, light-pink flowers borne above the foliage, vigorous branching, dark green foliage, and compact growth habit.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens, and hereinafter referred to by the cultivar name ‘Danharltpk’.

‘Danharltpk’ is a product of a planned breeding program and was originated from a hybridization made by the inventor, Gabriel Danziger, in a controlled breeding program in Mishmar Hashiva, Israel, in 1996. The female parent was an Impatiens cultivar designated O-381. The male parent was an Impatiens cultivar designated E-368. Both parents are proprietary cultivars used in the breeding program.

‘Danharltpk’ was discovered and selected as a flowering plant within the progeny of the stated cross by the inventor, Gabriel Danziger, in 1997 in a controlled environment in Mishmar Hashiva, Israel.

The first act of asexual reproduction of ‘Danharltpk’ was accomplished when vegetative cuttings were taken from the initial selection in 1997 in a controlled environment in Mishmar Hashiva, Israel by Gabriel Danziger. The cuttings are apical cuttings. No more than two expanded leaves and 3-4 immature leaves are evident. Horticultural examination of plants grown from these cuttings in Mishmar Hashiva, Israel, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.

BRIEF DESCRIPTION OF THE INVENTION

The following traits have been repeatedly observed and are determined to be basic characteristics of ‘Danharltpk’ which in combination distinguish this Impatiens as a new and distinct cultivar:

1. Large, round light-pink flowers borne above the foliage;

2. Vigorous branching;

3. Dark green foliage; and

4. Compact growth habit.

‘Danharltpk’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary significantly with variations in environment such as temperature, light intensity, and daylength without any change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Mishmar Hashiva, Israel under greenhouse conditions which closely approximate those generally used in commercial practice.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying color photographic drawing shows typical flower and foliage characteristics of ‘Danharltpk’, with colors being as true as possible with illustrations of this type.

DETAILED BOTANICAL DESCRIPTION

The measurements were taken in Mishmar Hashiva, Israel, and are based on plants grown from rooted cuttings in a net-covered greenhouse at temperatures of 30° C. maximum and 18° C. minimum. In the following description, color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), except where general colors of ordinary significance are used.
